Comme Deux Disco SkinIngredients explained
- A natural moisturizer that’s also in our skin
- A super common, safe, effective and cheap molecule used for more than 50 years
- Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
- Effective from as low as 3% with even more benefits at higher concentrations up to 20-40% (around 10% is a good usability-effectiveness sweet spot)
- High-glycerin moisturizers are awesome for treating severely dry skin
Butylene glycol, or let’s just call it BG, is a multi-tasking colorless, syrupy liquid. It’s a great pick for creating a nice feeling product.
BG’s main job is usually to be a solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin.
- Mandelic acid is an AHA that comes from bitter almond
- It can gently lift off dead surface skin cells and make the skin more smooth and even
- It has antibacterial properties
- It’s promising against acne and post inflammatory hyperpigmentation
- It’s light sensitive, so choose a product with opaque packaging
Synthetic Fluorphlogopite is the synthetic version of the super commonly used mineral, Mica. The advantage of being synthetic is that it has a more consistent quality, fewer impurities and an even lower heavy metal content than Mica (not that Mica's heavy metal content is high). It is also more transparent and has improved light reflection.
The two main use cases for Synthetic Fluorphlogopite is being used neat as a superior "filler" or skin tone enhancer or it can also serve as a base for multi-layered, composite pigments such as pearl effect pigments where it is coated with one or more layers of metal oxide, most commonly titanium dioxide.
Ci 77891 is the color code of titanium dioxide. It's a white pigment with great color consistency and dispersibility.
A kind of polymer (big molecule from repeated subunits) that helps to create beautiful gel-like textures. It's also a texturizer and thickener for oil-in-water emulsions. It gives products a good skin feel and does not make the formula tacky or sticky.
It works over a wide pH range and is used between 0.5-1.2%.
Citric acid comes from citrus fruits and is an AHA. If these magic three letters don’t tell you anything, click here and read our detailed description on glycolic acid, the most famous AHA.
So citric acid is an exfoliant, that can - just like other AHAs - gently lift off the dead skin cells of your skin and make it more smooth and fresh.
Far from the tin cans you find in the supermarket, Tin Oxide is mostly used when dealing with so-called effect pigments, tricky composite pigments that can do color travel (change color depending on the viewing angle) or give multiple color effect.
It's often found alongside Mica (as a base material) and Titanium Dioxide (as a coating) to give a glossy, pearlescent effect. Together, they make up a trademarked technology called RonaFlair Blanace from the German manufacturer Merck. According to their info, this combination can balance out undesirable tones in the skin, making it a popular choice for brightening products and highlighters.
Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product.
It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water.
The unfancy name for it is lye. It’s a solid white stuff that’s very alkaline and used in small amounts to adjust the pH of the product and make it just right.
For example, in case of AHA or BHA exfoliants, the right pH is super-duper important, and pH adjusters like sodium hydroxide are needed.
It’s pretty much the current IT-preservative. It’s safe and gentle, but even more importantly, it’s not a feared-by-everyone-mostly-without-scientific-reason paraben.
It’s not something new: it was introduced around 1950 and today it can be used up to 1% worldwide. It can be found in nature - in green tea - but the version used in cosmetics is synthetic.
